M871 Hippuris vulgaris - Mixed Boreal Aquatic Vegetation Macrogroup
Type Concept Sentence: Aquatic freshwater vegetation found in shallow to deep water within the Arctic and Boreal climate zones of Alaska, Canada and Greenland with dominant species such as Isoetes tenella, Limosella aquatica, Potamogeton spp., Ranunculus ssp., and Sparganium angustifolium.
Common (Translated Scientific) Name: Common Mare''s-tail - Mixed Boreal Aquatic Vegetation Macrogroup
Colloquial Name: Boreal Freshwater Aquatic Vegetation
Hierarchy Level: Macrogroup
Type Concept: This aquatic floating and rooted vegetation is found in freshwater lakes, ponds and sluggish rivers of the Arctic and Boreal climatic zones of Alaska, Canada and Greenland. It occurs in 10 cm (4 inches) to at least 3 m (10 feet) of freshwater. Dominant species include Hippuris vulgaris, Isoetes tenella, Limosella aquatica, Potamogeton spp., Ranunculus ssp., and Sparganium angustifolium. This macrogroup includes nonvascular cryptogram or moss communities. Emergent species are absent or rare. These species are typical of aquatic habitats, and do not appear to be restricted to arctic or boreal climates.
Diagnostic Characteristics: Aquatic bed vegetation in arctic and boreal climatic zones.
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: These species are typical of aquatic habitats, and do not appear to be restricted to arctic or boreal climates.

Physiognomy and Structure: Floating and rooted aquatic vascular and nonvascular plants, submerged and up to 15-20 cm (6-8 inches) above the water surface.
Floristics: Dominant species include Callitriche heterophylla (= Callitriche anceps), Chara spp., Hippuris vulgaris, Isoetes tenella (= Isoetes muricata), Limosella aquatica, Potamogeton alpinus, Potamogeton pusillus ssp. tenuissimus (= Potamogeton berchtoldii), Stuckenia filiformis (= Potamogeton filiformis), Potamogeton gramineus, Stuckenia pectinata (= Potamogeton pectinatus), Potamogeton perfoliatus, Ranunculus gmelinii, Ranunculus hyperboreus, Ranunculus pallasii, Ranunculus trichophyllus, Ruppia cirrhosa (= Ruppia spiralis), Sparganium angustifolium (= Sparganium multipedunculatum), and/or Subularia aquatica. This macrogroup includes nonvascular cryptogram or moss communities dominated by bryophytes Sarmentypnum sarmentosum (= Calliergon sarmentosum), Fontinalis antipyretica, and Scapania paludosa and lichen Siphula ceratites. Emergent plants are absent or rare.
Dynamics: These aquatic communities in shallow water are eventually replaced by marshes, wet meadows, or bog meadows.
Environmental Description: This macrogroups occurs in permanent and seasonally ephemeral bodies of freshwater such as ponds, lakes, slack waters of large rivers. Water depths range from 10 cm (4 inches) to at least 3 m (10 feet) deep, and occur within arctic and boreal climate zones. Substrates are mineral, organic-rich muck, or rock.
Geographic Range: This macrogroup is found in the Boreal and Arctic climatic zones of Alaska, Canada and Greenland.
